The answer, as recorded

## My actual recommendations, in order **1. Blumira** - my default pick for most small businesses. It was built from the ground up as a cloud SIEM for SMBs, ships with pre-built detections maintained by their SecOps team, and includes a human on-call for critical findings. Deployment is days, not months. Pricing starts around **$12/employee/month**, and there's a free tier for Microsoft 365 logging. You get SIEM value without hiring a security analyst, which is the actual constraint for most small businesses. **2. Huntress Managed SIEM** - best if you want someone else watching the alerts. Huntress is explicitly built for sub-200-employee orgs and the MSPs serving them. Managed SIEM runs about **$4/data source/month** (10 GB pooled per source) on an annual term, with a 50-unit minimum. Pairs naturally with their Managed EDR (~$8.99/endpoint) - and honestly, if you don't have EDR yet, buy that *before* a SIEM. **3. Microsoft Sentinel** - the right answer if you're already a Microsoft 365 E5 / Defender shop. Defender XDR alerts, Entra sign-in and audit logs, Office 365 audit logs, and Azure Activity logs all ingest **free**, so your actual bill can be small. Everything else is ~$2.46/GB pay-as-you-go, with a 10 GB/day free trial for 31 days. The catch: costs spike fast once you add non-Microsoft sources, and it expects someone who can write KQL. **4. Wazuh** - the free, open-source option. Genuinely capable (SIEM + XDR + file integrity monitoring + compliance reporting), and it has the strongest small-business adoption of the bunch. But "free" means your time: you self-host, tune the rules, and respond to everything yourself. Pick it if you have a technical person who *wants* this project, not to save money on paper. **5. Sumo Logic** - reasonable cloud-native middle ground with a free tier, but the paid tiers get expensive per GB. Worth a look mainly if you're already using it for ops/log analytics and want to extend into security. ## The honest caveat If you're a small business without a dedicated security person, a raw SIEM will generate alerts nobody reads - that's the common failure mode. Prioritize in this order: MFA everywhere → EDR (Huntress, CrowdStrike, Defender for Business) → **then** SIEM, and strongly prefer a *managed* one. Options 1 and 2 above are managed; 3-5 are not. Also: if a compliance framework (SOC 2, CMMC, PCI, cyber insurance) is what's driving this, check which log retention period the framework requires before you price anything - retention, not ingestion, is usually what blows up the bill.
